What to know before buying

Listing details to confirm

The listing describes 1m in the title, while its details list 3.3 Feet. These are approximately equivalent lengths, but the product length is presented inconsistently. The title gives 4K 60Hz and the feature text specifies 3840*2160, while video output also requires DisplayPort Alt Mode support from the connected device. Confirm the capability of the intended device and setup, especially with docks, because customer feedback on connection, video output and docking-station compatibility is mixed. The listing also uses both USB and Thunderbolt terminology, without establishing that every Thunderbolt feature is supported.

Who is it for?

A good fit for

People who need a short USB-C extension for a compatible laptop, smartphone or tablet.
Setups requiring listed USB-C charging up to 100W, data transfer up to 10Gbps or compatible 4K 60Hz video.

Less suited to

Buyers who need guaranteed operation with a particular dock or video setup without first confirming device compatibility.
Anyone needing a longer cable than the approximately 1m length indicated by the title and feet measurement.

The listing claims up to 4K at 60Hz for devices with DisplayPort Alt Mode. Check that the connected source supports this mode.
